Set in 15th century Europe, this is the tale of the meeting of two menTheobold and Erhardknights in two hostile armies, who are placed in circumstances in which they are forced to learn Jesus' principle from the Sermon on the Mount: "But I say unto you, love your enemies, bless them that curse you, do good to them that hate you". Written and first published in 1871, the author allows the light of lives transformed by the grace of God to beautifully shine, as one known among men for being "Iron-Hearted" desires a softened heart given by God, and the Holy Spirit to teach him to have a childlike submission to his true King, Jesus. This volume is one of the eleven titles in the "Children's Character-Building Collection", our popular reprints of 19th-century Christian books for young children.
